Summary:

Preliminary Flood Risk Assessment (PFRA) aims at assessing the scale of flood risk for river basin areas. Furthermore, it focuses on identifying the risk of flooding in these areas. The areas subject to flood risk have been indentified on the basis of inventory works carried out at national, provincial and local level. The inventory covered information on the borders of flood hazard areas, hydrographic maps, spatial management plans and information on the condition of flood control structures. The inventory was based on questionnaires. The collected material was grouped and presented hierarchically depending on the type of flood. Then, it was reduced to a single frame of reference and a uniform scale. The gathered data is the basis for indicating sections of rivers for which flood hazards maps and flood risk maps will be developed.
The Preliminary Flood Risk Assessment (PFRA) was developed under the project 'Global Monitoring for Environment and Security' (GMES). It is a part of the fulfillment of the obligations of Poland towards UE in implementing the first phase of Flood Directive. The paper presents the development of PFRA for the upper and middle Odra River.
